Vietnamese feudal schools served the purpose of preparing people to manage the country. Educational content and approach were centered on state management attitudes and skills; schools (both state-owned and private - The Master) did not officially offer health education courses. However, the remaining textbooks and learning papers demonstrated that feudal schools prioritized health education, initially incorporating health education content into teaching at all levels. Health education comprised knowledge and skills for maintaining health, as well as creative encounters with Eastern medicine in illness prevention, conservation, and human health improvement. The content and methods of health education demonstrated that medieval schools sought to develop people holistically in terms of knowledge, skills, and attitudes. The knowledge and methodology of health education in ancient feudal schools not only help us understand the history of Vietnamese education, but they also provide many lessons acquired in the development of today's educational system.
